I will always love United Offensive, it was the first game I ever played online. Modding the game got me into programming and managing servers led me to networking and got me to the career that I have today. I’m not a game pass subscriber but it would great for more people to be able to experience it
I’m pretty sure that there are serious vulnerabilities in the netcode of the original MW that makes playing it online on PC unsafe. I haven’t ever seen an authoritative source confirm it however the last time I tried to play it online probably 4 years ago. There were all sorts of malicious redirects when trying to join servers from the browser
